This is a “hybrid” Hackathon‐Datathon competition organised by the ENGAGE FP7 Project. Applicants will have the opportunity to register for the competition and then submit their entries, which can be open‐data‐centric applications and/or innovative, curated and re‐usable high‐quality datasets. All applicants must conform to the Eligibility Criteria stated below and all entries will be assessed based on the Selection Criteria. A panel of judges appointed by the ENGAGE consortium will assess the entries and decide on a winner and runner‐up for the Hackathon and the Datathon.
